Anyone who plays MMORPG long enough starts to wish things were different in the game, or that something was added or removed. If you were making your own MMORPG name a few things that would make it standout or great or different from whatever game you play now. Be as creative as you want, go as in depth as you want, list as many things as you want. I'll start.
I would put a HUGE focus on character customization, almost endless dress up opportunities, nick naming your items, getting tattoos, lots of crazy hairstyles lots of color pallettes for skin teeth hair eyes etc.
I would factor in combat bonuses for terrain & flank. Fighting in water or quicksand might prove difficult.
I would let the terrain be permanently scarred or destroyed in some cases. If lightning struck a tree, that tree might split in half or cause a fire or something.
